Abstract:
The coronary venous system offers a route for mapping and ablation of ventricular arrhythmias with suspected epicardial or intramural origins. Coronary venous mapping helps the operator to select the best ablation approach, decide when percutaneous epicardial access may be necessary and provides an opportunity for therapeutic interventions, including radiofrequency application inside the coronary veins or ethanol infusion. In this article we review the anatomy of the coronary venous system, the scenarios in which coronary venous mapping can be helpful and the technical aspects involved in coronary venous mapping.

01:28Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
